A pair of slides 325 and 326 (Fig. 8) are guided respectively on the columns 32, 34 and on the columns 33, 35. Each pair of slides are connected by a cross bar 328, and

spur gear 293 is fastened to the the latter have fastened thereto the series of nail holders 330. Guide strips 335 bear up against the lower surface of each series of nail holders 3'30 and are fastened at their ends to the pair of slides 325 and 326,,constituting floating guides for the side and ends of the boxes to be made. Guide strips 336 are connected to the slides 325 and 326. One of the guide strips 336 is securely fastened to the slides 325 and 326, while the other guide strip 336 is fastened to the angle shaped levers 337 (Fig. 13) that are pivoted to the slides 325, 326. Springs 338 on pins 339 bear against the angle shaped lever 337. By this means the ends and sides of the boxes are adjustably guided. .Guides 340 and 341 extend from eachof the slides 325 and 326 and'are connected tothe guide strip 335. A channel bar 342 is fastened to each cross head 300 and 301 and from which are suspended the punches 343. The lower ends of the punches 343 enter the nail holders 330. Nail feeding conduits 345 extend from the nail feeders 246, 248 and connect with the nail holders 330.

To operate-the machine as far as described two stacks or series of boards 350 of the requisite 1 dimensions are placed in the charging hopper, one stack located on-each side of the partition 97. The main shaft 85 is rotated by means to be described sub-- sequently. With the rotations of the shaft 71 oscillates the arm 72 and by means of the link 57 the end feeding cross head 52 receives its reciprocations. With the reciprocations of the cross head 52, the pusher ends of the dogs'64 carry with each for ward stroke one of the boards 350through the feed opening 100 and lands'a pair of said boards on the tipping d0or 68. In case the boards 350 which form the ends of the box to be made in any way interfere with the cross head 52 meshing its full stroke, the locking pin 73 disengages from the cavity 78 in the lug 79 andthe shaft 71 is permitted to oscillate while the said cross head remains stationary. c

The rotations of shaft 85 with the cam 86 causes the lever 87 to swing, and thereby the tipping doors 68 are tipped through the intervention of the links 90, and the springs 92 thereon. In case of any disarrangement of the boards on the said doors, or if for any other reason the doors cannot be tipped, the springs 92 will compress and allow. the

lever 87 to swing, while the doors remain inoperative. the doors 68 the boards .350 are brought from horizontal to vertical positions. While the boards are tipped from a horizontal to a vertical position their upper ends are en- By reason of the tipping of gaged by the swinging guide arms 111, while their forward ends are guided by the guide strips 94, and after they pass said arms are vertically held in place as indicated in Fig. 5. The boards 350 are next engaged by the fingers 151 and horizontally moved, to be locatedin proper position opposite the end of the pusher plate 203 under the crown 177 of the hood, the latter swinging. on the screws 179 in case the'end boards 350 are- 1 irregular in height. The fingers 15 1- are horizontally moved by reason of the reciprocations of the crossheads 142. The latter are moved by reason of the oscillations of .thearms 1,37, and the movementsof the connecting rods 150. Upon the return strokes of the cross heads 142, that is to say toward the chargingend of the machine, the pusher plate 203 moves one of the sides 351 (see Fig. 2) in proper position over the ends 350 The pusher plate 203 reciprocates with the cross head 205. The cross head 205 receives its movements by virtue of the hook end 216 of the link 215 engaging the pin 214. The link 215 is moved by reasonfof the oscillations of thearm 125. On'the next forward stroke of the cross heads 142 the end boards 350 are engaged by the vertical pushers 152 and are brought under and below the guide strips 335, being guided in the channel irons 174., At the same time the pushers 161 and 162 engage the side boards 351 to locate them over the end boards 350. r The end boards strike the regulating finger 237 which causes the finger242, to engage the spring latch 229,

and therefore the spring latch 229 does not actuate the heel 230. The shaft 223 is then not oscillated and the plunger 232. is not raised and the hook end 216 remains locked with the pin 214. Thereby the actuating mechanism of .thepusher plate 203 is not disturbed. In case no end board 350 is fed to engage the regulating finger237, the

350 on one side during their movements spring latch 229 engages the heel 230,- and the shaft 223 is oscillated. Thiscauses the plunger 232 to disengage the hook end 216 from the-pin 214 and thereby the link 215 reciprocates while the cross head 205 remains stationary. The roller 218 now bears on the guide plate 208. By these means none of the'side boards 351 are moved during the cessations of the movements of the end boards 350.

When both the series ofboards 3,5,0 and 351 are brought under the guide strips 335 they are in proper position for the punches to nail one of the sides to a pair of ends.

During the return strokes of the oscillating bearing 243, the latter strikes the collar 245, and thereby the arm 268 is swung, which oscillates the shaft 261. By means of the oscillations of the shaft 261, the vertical links 256 and 265 are moved, and the latter operate the mechanism of the nail feeders 246 and 248. The nails are then allowed to drop through the nail feeding conduits 345 andreach the nail holders 330. The reciprocations of the cross heads 300 and 301 cause the punches 341 to hammer the nails so that a pair of ends 350 and a side 351 are nailed together.

l/Vhen the cross head 205 does not reciprocate, the oscillating bearing 243 remains stationary and the nail feeding mechanism remains inoperative.

The second unit indicated in its entirety by the letter B is shown with the horizontal sides 360, 361 (Fig. 18) similar to 30 and 31 which are respectively connected to the guide columns 34 and 35. The sides 360, 361 at their other ends are respectively connected to guide columns 362, 363 similar to 32 and 33. A fourth pair of guide columns are indicated at 364, 365. The columns 362 to 365 are bolted to a bed plate 366. A plate 367 similar to 36 connects the columns 362, 364 and a plate not shown similar to 37 connects the columns 363 and 365. A cross brace 371 connects the columns 362 and 363, and a cross brace 372 connects the columns 364, 365. The shaft 85 is continued for the second unit B by means of the coupling 376. (Fig. 1).

Journal brackets 377 are connected to the sides 360, 361 and support a rock shaft 378 having extending therefrom the turning fingers 379 and 380. A rock shaft 382 is journaled in sides 360, 361 and has fastened thereto the bifurcated arm 385, in the lower end of which latter is journaled the roller 386. An arm 387 extends from the rock shaft 378 and, a link 388 has its ends pinned to the arms 385 and 387. A cam 390 on the shaft 85 engages the roller 386. A spring 392 extends between the arm 387 and the floor. A'pair of angle irons 395 are fastened to the horizontal sides 360 and 361. The

. vertical flange of each of the latter angle position.

not shown. Screws similar to 175 adjustably support the angle irons 395.

The main driving shaft 85 is j ournaled in bearings 400 formed in the columns 362 and boxes 423 and 424 which extend up from the bed plate 366. An arm 425 has one end fastened to the shaft 422. One end of the connecting rod 421 is pinned to the arm 425. A bevel gear 430 is fastened to one end of the shaft 422. Supporting boxes 431, 432 have supported therein the short cross shaft 433. A bevel gear 434 fastened to the shaft 433 meshes with the bevel gear 430. By means of the connections interposed between the main shaft 85 and the shafts 422 and 433 an oscillating movement is given to the latter two shafts, from the rotations of the former. Levers 437 and 438 have each one end fastened to the cross shaft 433. Cross heads 442 bear on shelves 443 formed with the horizontal sides 360 and 361.
